IMPROVEMENT IN REFRIGERATING BUTTER-CASES.

Specification forming part of Letters Patent No. 215,984, dated May 27,1879; application filed September 29, 1877.

To all whom it may concern:

Be it known that I, EUGENE swarm, of Rose Hill, in the county of Mahaskaand State of Iowa, have invented a certain new and useful Improvement inRefrigerating Shipping-Gases for Butter-Tubs; and I do hereby declarethat the following is a full and clear description of the same, whichwill enable .others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure l is a plan or top viewof my improved refrigerating shipping-case with the lid open, and Fig. 2is a vertical section of the package closed.

Similar letters of reference indicate corresponding parts in both thefigures.

This invention relates to refrigerating boxes or packages adapted fortransportation; and

consists in constructing the bottom and hinged cover of a box of thisclass with diagonallyarranged ribs, substantially as and for the purposeherein after fully described, an d pointed I out in the claim.

In the drawings, A is a square or rectangular box, made of wood, thesides of which are mortised together to make a solid and substantialpackage provided with a hinged lid or cover, B.

The bottom of the box A, as well as the inner side of its cover B, isprovided with. a series of diagonal slats or bars, denoted by a and b,respectively, and thesides of box A are faced on'the inside with'vertical slats or bars 0 0, cut off a short distance below the upperrim or edge of the box to leave room for the bars a of the cover, which,when this is closed, will project some distance'into the box.

0 G are two parallel partitions arranged vertically in box A with theirlower edges resting upon the diagonal bars it in the bottom of the box.That part of the sides of box'A between these partitions is without thevertical bars 0, as will be seen by reference to Fig. 1 and by thesepartitions O G, which are permanent, the box is divided into threecompartments, E F G, the middle one of which, F, is to contain the ice,while the butter-tubs, denoted byD in the drawings, are piled in the endcompartments, E G.

The covers of the butter-tubs D are formed with an upward-projecting rimor ledge to receive the bottom of the tub next above; and the tubs areof such a size that they will fit snugly into the compartments E G whenarranged in a row therein, as shown in Fig. 1, to prevent undue shakingduring transportation.

I am well aware that it ismot new to con struct refrigerators orrefrigerating shippingpackages for containing butter, fruit, &o., withribs upon the sides or bottom; but this construction I do not claim,broadly. My improvement consists in placing said ribs or bars diagonallyupon the inner side of the hinged cover and bottom, by which they notonly form grooves or channels for the circulation of the cooling mediumin like manner as when ribs parallel to the sides are used, but alsoserve as braces for the lid B and the bottom of box A, respectively, soas to greatly strengthen the package, which is of importance in ashipping-case of this kind, containing a heavy weight unequallydistributed, (the filled firkins in the end chambers weighing more thanthe ice in the narrow middle comp'artment,) and which is apt to beknocked about and subjected to rough usage While in transit.

Having thus described my improvement, I claim and desire to secure byLetters Patent of the United States- In a refrigerating shipping case orpackage constructed substantially as described, the bottom and hingedcover provided upon their inner sides with diagonal ribs or bars b a, asand for the purpose set forth.
